The prototype device contains an electric circuit as well as red light-emitting diodes for a display, though it does not yet light up. The lenses were tested on rabbits for up to 20 minutes and the animals showed no adverse effects.

The tested lenses don't really do much, but it sounds like contacts with a relatively basic HUD might only be a few years away. I've been waiting for something like this for years.

I thought of this years ago, whether they would be able to put computer technology into contact lenses... that is super cool. Apart from all kind of cool cyber-punk-esque possibilities, it also opens up countless possibilities for slacking off at work/in class.
